Wowsome of these posts are old! but the 2 litre hyundui head is the same as a 1g, but have a close look at the inlet manifold i think you will find the plenum and runners are a lot bigger, could have real possibilities!! more than the 1G for bigger performance.
i have a 1.8 head that i was going to use, the head looks the same as the 2.0 head. i didnt really look at the intake manifolds. they look the same to me, but i didnt look close
what a nice port job, probally hurt it more than i helped it.
